September 11 Attacks

US president Barack Obama signs into law legislation ending spy agencies' bulk collection of Americans' telephone records, reversing a national security policy that had been in place since shortly after the September 11 attacks in 2001.

The United States has marked 12 years since hijacked jetliners crashed into the World Trade Centre, the Pentagon, and a Pennsylvania field with bagpipes, tolling bells and a reading of the names of the nearly 3,000 people who died.

A disgruntled airport security screener has been arrested in California in connection with threats made against Los Angeles International Airport ahead of the 9/11 attacks anniversary.

Nna Alpha Onuoha, 29, was detained by members of the Los Angeles Joint Terrorism Task Force after triggering an alert at the airport earlier in the day which prompted certain terminals to be evacuated, the FBI said in a statement.

Mr Onuoha had resigned from his job as a transportation security administration screener after recently being suspended from the position.
